Hey dudes, I paid someone $60 last year to solder up whatever resistor we thought was needed on to the board for my tach to work properly on my gauge cluster...
Checked that the tach is working on tuner studio and the output or whatever it's called is also set "on" , yet my tach doesn't work... This guy bailed on me and hasn't answered any messages or calls so that sucks, but I'd still like to have a functional tachometer on my miata..

FYI: I purchased the ecu used from someone who purchased it used from a megasquirt employee in atlanda who built it.

Wondering if there's someone knowledgeable about this who is willing to let me come to them, or them come to me and figure it out..
